Chromatographic silica gel powder for separation and purification, 300-400 mesh

300-400 mesh silica gel is a specialized silica gel used for purification, separation, and catalyst support.

Silica gel is an amorphous silicon dioxide with highly active adsorption properties, commonly used as a desiccant, adsorbent, catalyst carrier, etc. The mesh number of silica gel refers to the particle size that can pass through a sieve; the higher the mesh number, the finer the particles. 300-400 mesh silica gel features high purity, high activity, and strong adsorption capacity, making it widely applicable in chemical, pharmaceutical, and environmental protection industries.
